Estimated Annual Consumable Costs
We don’t publish typical costs or change intervals here: prices move, and service intervals come from each car’s own maintenance schedule. Check the handbook for intervals and compare current prices before you buy.
Which Is Cheaper to Maintain?
For routine consumables like wipers, bulbs, and filters, the Honda Civic and Mazda Mazda3 are very similar in cost. The key differences come down to:
- Oil spec — grade and specification vary by engine on both cars (see each oil guide). Some specifications require pricier oil.
- Battery type — start-stop cars need EFB or AGM batteries which cost more than standard ones.
- Spark plugs — iridium plugs cost more but last much longer than standard copper.
Frequently Asked Questions

How we check fitment for this guide
We cross-reference fitment figures against manufacturer specifications and OE-supplier catalogue data where available, and matched to the standard codes that actually govern fit — battery type/group sizes, wiper lengths and fitting types, bulb fitment codes, tyre size markings, and oil specifications. We work by make, model, year, engine, and build date, because a single model can take different parts across its life. Where the right part depends on your exact vehicle, we tell you to confirm by registration or VIN. More on our method →
